Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of:
1 m/s to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg/s2 |
|
1 mph to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg |
Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.
An endoskeleton (internal skeleton) is a charateristic of __________ animals, including humans.
vertebrate |
|
spiny |
|
arthropod |

In cell biology, cytokinesis results in two separate:
nuclei |
|
chromatids |
|
cells |
|
chromosomes |
During cell division, the cytokinesis phase occurs when cytoplasm and cell membranes complete their separation resulting in two separate cells.
The envelope of gases surrounding the planet is called the:
lithosphere |
|
atmosphere |
|
geosphere |
|
hydrosphere |
The biosphere is the global ecological system integrating all living beings and their relationships. This includes their interactions with the lithosphere (the rigid outer part of the earth, consisting of the crust and upper mantle), hydrosphere (all surface water), and atmosphere (the envelope of gases surrounding the planet).
An element in the physical state of __________ maintains a constant volume and shape.
gel |
|
gas |
|
liquid |
|
solid |
An element in a solid state has atoms or molecules that are constricted and do not move freely. Solids maintain a constant volume and shape and exist at a lower temperature than liquids or gases.
